condit. format: If date in cell = today, display "Today"

What I want is simple, but I don't seem to be able to produce it, so I'm wondering if it's possible.

In a given cell, I have a date. I want to use conditional formatting so that if the date in the cell is today's date, the cell displays "Today" instead of the date.

So, for example, I have "2/14/2013" in Cell A1. When I open the sheet on 2/13/13 or 2/15/13, the cell reads "2/14/2013"; if I open it on 2/14/13, it says "Today"

Is this possible?

Thanks.

I don't think I was clear. I want the word "Today" to appear in the cell, not a value.
